Description

Technical Field

[0001] The present invention relates to the technical field of anti-corrosion of doors and windows, and particularly to a surface anti-corrosion spraying treatment device for grain depot doors and doors and windows. Background Art

[0002] As important components in buildings, doors and windows undertake functions such as protecting the indoor environment, enhancing the aesthetics of the building, and increasing lighting and ventilation. Doors and windows are often exposed to the external environment and are easily eroded by natural factors such as rain, sunlight, and sand. Therefore, anti-corrosion treatment is required for doors and windows;

[0003] The doors and windows of grain depots also need anti-corrosion treatment. However, there are often oil stains, dust, or other impurities on the surface of the doors and windows that will affect the spraying effect. The surface needs to be cleaned and treated in advance. At the same time, after cleaning, it is also necessary to wait for the water stains to dry before spraying the anti-corrosion material; since the doors and windows of grain depots are much larger than those of residential buildings, when spraying, the entire door and window need to be sprayed in several steps.

[0004] During the cleaning process, impurities on the doors and windows may remain on the device, resulting in the impurities affecting the final anti-corrosion effect during the subsequent anti-corrosion spraying process. Summary of the Invention

[0038] In the following description, many specific details are set forth to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0039] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that can be included in at least one implementation manner of the present invention. The "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is separate from or selectively exclusive of other embodiments. Embodiment

[0040] Refer to Figures 1 to 7, which is the first embodiment of the present invention. This embodiment provides a surface anti-corrosion spraying treatment device for grain storage doors and doors and windows, which includes a horizontal moving mechanism 600 for driving the anti-corrosion spraying device to move horizontally;

[0041] a vertical moving mechanism 700 for driving the anti-corrosion spraying device to move up and down. The horizontal moving mechanism 600 is located at the upper end of the vertical moving mechanism 700;

[0042] It is characterized in that it includes an anti-corrosion mechanism 100, a drying mechanism 200, a cleaning mechanism 300 and a rotating frame 400. The drying mechanism 200 is arranged between the anti-corrosion mechanism 100 and the cleaning mechanism 300. The rear end of the rotating frame 400 is connected to a rotating mechanism 500 through a rotating head 402; the anti-corrosion mechanism 100, the drying mechanism 200 and the cleaning mechanism 300 respectively perform the work of cleaning, drying and anti-corrosion spraying, and the three work simultaneously during the horizontal movement of the rotating frame 400 through the horizontal moving mechanism 600;

[0043] The rotating head 402 can drive the upper driving part 205 and the lower driving part 204 respectively arranged above and below it. The first baffle 202 and the second baffle 211 in the drying mechanism 200 are driven to move by the upper driving part 205, so that the first baffle 202 and the second baffle 211 present different states during the operation and stop of the spraying device; the first lead screw 206 in the drying mechanism 200 is driven to rotate by the lower driving part 204; the first lead screw 206 is movably connected to a plurality of scraping rings 207 sleeved on the water-absorbing felt 203;

[0044] Preferably, the water-absorbing felt 203 is a cylindrical felt. When the scraping ring 207 moves downward along the water-absorbing felt 203, the water in the water-absorbing felt 203 and some impurities on the felt will be squeezed out.

[0045] Preferably, a plurality of scraping rings 207 are equidistantly distributed on the water-absorbing felt 203, and each scraping ring 207 is responsible for the extrusion and cleaning work of a section of the water-absorbing felt 203 to ensure that the entire water-absorbing felt 203 can be cleaned.

[0046] The first baffle 202 is provided with a through hole 202a.

[0047] The drying mechanism 200 includes a blower 201, and the blower 201 is placed outside the rotating frame 400;

[0048] The first baffle 202 and the lower driving part 204 are placed in the middle of the rotating frame 400. An electric heating plate 208 is arranged between the first baffle 202 and the lower driving part 204. The open side of the electric heating plate 208 is provided with a water-absorbing felt 203, and a first lead screw 206 is arranged between the water-absorbing felt 203 and the electric heating plate 208;

[0049] Preferably, the heating plate 208 requires an external power supply, which is not shown in the figure.

[0050] Preferably, during the operation of the device, the first baffle 202 and the second baffle 211 will protrude forward, playing a certain blocking role on both sides of the water-absorbing felt 203. During the operation of the device, the second baffle 211 can effectively block the water sprayed by the second nozzle 303, preventing the water-absorbing felt 203 from being wetted and losing its function of adsorbing moisture on the doors and windows.

[0051] It should be noted that the outer end of the lower driving member 204 of the first baffle 202 should not exceed the water-absorbing felt 203.

[0052] Blocking blocks 209 are provided at both the upper and lower ends of the first baffle 202 and the lower driving member 204. The blocking blocks 209 are used to block the drainage port 210, and the drainage port 210 is located at the port of the rotating frame 400.

[0053] The upper driving member 205 includes a first movable shaft 205d, a first threaded shaft 205e, and a second threaded shaft 205f. One end of each of the first movable shaft 205d, the first threaded shaft 205e, and the second threaded shaft 205f is movably connected to the rotating frame 400; a upper driven gear 205a is provided at the other end of the first movable shaft 205d, a first side gear 205b is provided at the other end of the first threaded shaft 205e, and a second side gear 205c is provided at the other end of the second threaded shaft 205f; threads 205g are provided on both the first threaded shaft 205e and the second threaded shaft 205f, and the rotation directions of the two threads 205g are opposite;

[0054] Both the first baffle 202 and the lower driving member 204 are movably connected to the two threads 205g through a movable joint 205h respectively.

[0055] Preferably, the upper driven gear 205a is placed in the middle and meshes with both the first side gear 205b and the second side gear 205c.

[0056] The lower driving member 204 includes a second movable shaft 204a. One end of the second movable shaft 204a is movably connected to the rotating frame 400, and a lower driven gear 204b is provided at the other end. A first transmission head 204c is also provided on the second movable shaft 204a. The first transmission head 204c and the second transmission head 204e are driven by a crawler 204d. The second transmission head 204e is located at one end of the transmission shaft 204f, and the other end of the transmission shaft 204f is connected to the first lead screw 206 through a bevel gear set 204g.

[0057] Preferably, the outside of the transmission shaft 204f is movably connected to the bottom surface of the outer frame 401 through a protrusion, and the function of the protrusion is to fix the position of the transmission shaft 204f.

[0058] On the inner side of the first baffle 202, there is a through port 202a.

[0059] The rotating frame 400 includes an outer frame 401. At the rear end of the outer frame 401, there are a clamping groove 403 and a rotating head 402. The first baffle 202 and the second baffle 211 move within the clamping groove 403.

[0060] The rotating head 402 includes a rotating head main body 402a. In the middle of the rotating head main body 402a, there is a clamping groove 402d. At the edge of the end of the rotating head main body 402a, there are a first arc-shaped tooth head 402c and a second arc-shaped tooth head 402b.

[0061] Preferably, the length of the first arc-shaped tooth head 402c is much smaller than the length of the second arc-shaped tooth head 402b, and there is a gap between the first arc-shaped tooth head 402c and the second arc-shaped tooth head 402b.

[0062] It should be noted that the gap between the first arc-shaped tooth head 402c and the second arc-shaped tooth head 402b determines the rotation angle of the rotating mechanism 500 before the next operation, that is, rotating the rotating frame 400 to the horizontal state, which is 30 degrees in this embodiment.

[0063] It should be noted that after the rotating frame 400 completes the anti-corrosion spraying work for one row, it needs to rotate clockwise by 210 degrees. Then, it starts the cleaning and anti-corrosion spraying work for the next row; during the process of the rotating head 402 rotating clockwise by 210 degrees, the first arc-shaped tooth head 402c meshes with the upper driven gear 205a, driving the first side gear 205b and the second side gear 205c to rotate through the upper driven gear 205a; at the same time, the second arc-shaped tooth head 402b meshes with 204b, ultimately driving the first lead screw 206 to rotate;

[0064] It should be noted that the rotating mechanism 500 controls the rotating frame 400, that is, the rotating head 402 rotates by 210 degrees.

[0065] The anti-corrosion mechanism 100 includes a material box 101. On one side of the material box 101, there is a first pump 102. The anti-corrosion mechanism 100 also includes a first spray head 103, and the first spray head 103 is placed inside the rotating frame 400;

[0066] The cleaning mechanism 300 includes a water tank 301. On one side of the water tank 301, there is a second pump 302. The cleaning mechanism 300 also includes a second spray head 303, and the second spray head 303 is placed inside the rotating frame 400.

[0067] The rotating mechanism 500 includes a driving motor 501. A driving gear 506 is provided at the output end of the driving motor 501. Above the driving motor 501, there is a rotating shaft 502. One end of the rotating shaft 502 is movably connected to a vertical frame 503, and the bottom surface of the vertical frame 503 is fixed to a bottom plate 504; the driving motor 501 is fixed to the vertical frame 503; at the other end of the rotating shaft 502, there is a clamping joint 507. On one side of the clamping joint 507 close to the vertical frame 503, there is a transmission gear 508, and the transmission gear 508 is fixed to the rotating shaft 502; the transmission gear 508 and the driving gear 506 are driven by a transmission rack 509; the output end of the driving motor 501 is supported by a support rod 505.

[0068] Preferably, the size of the driving gear 506 is much smaller than that of the transmission rack 509. Therefore, the transmission rack 509 will rotate slowly to prevent the rotating mechanism 500 from driving the rotating frame 400 to rotate too fast.

[0069] The horizontal movement mechanism 600 includes a second lead screw 601. One end of the second lead screw 601 is connected to the output end of a rotating motor 602, and the other end is movably connected to a bracket 603.

[0070] During use, the first baffle 202 and the second baffle 211 are in the extended state during the operation of the device. At this time, the anti-corrosion mechanism 100 and the drying mechanism 200 are in a connected state. The rotating frame 400 drives the cleaning mechanism 300, the drying mechanism 200, and the anti-corrosion mechanism 100 to perform cleaning, drying, and anti-corrosion spraying in sequence. During the work process, the water-absorbing felt 203 rolls along the surface of the door and window. One side of the water-absorbing felt 203 that fits the door and window adsorbs moisture, and the other side is dried by the electric heating plate 208; when the anti-corrosion treatment of a row of areas on the surface of the door and window is completed, the cleaning mechanism 300, the drying mechanism 200, and the anti-corrosion mechanism 100 stop working. At this time, the rotating mechanism 500 drives the rotating frame 400 to rotate clockwise by 210 degrees. During the rotation, the first baffle 202 and the second baffle 211 are retracted along the thread 205g through the movable joint 205h. At the same time, each scraping ring 207 squeezes and scrapes a certain distance along the water-absorbing felt 203 from top to bottom;

[0071] Before the cleaning mechanism 300 works on the door and window for the next time, the rotating mechanism 500 controls the rotating frame 400 to rotate counterclockwise by 30 degrees. At this time, the rotating frame 400 is in a horizontal state and starts to work. The subsequent work process is the same as the above content, but the rotation direction is opposite.

[0072] In summary, when the device performs anti-corrosion treatment on doors and windows, it goes through high-pressure water gun cleaning, drying, and finally anti-corrosion material spraying. During the operation of the device, the dried chamber is connected to the anti-corrosion spraying chamber through the through-port 202a to accelerate the air-drying rate of the anti-corrosion material. At the same time, during the process of the device performing line-changing spraying, a cleaning operation is carried out on the water-absorbing felt 203 of the device to prevent excessive impurities and moisture from being adsorbed on the water-absorbing felt 203. At the same time, the drainage port 210 that plays a drainage role is opened to accelerate the water drainage effect.
